Inside Security (insert)

I've changed it up just a few hours ago to reflect the following in menu.ipxe - which works great:

set 209:string http://###.###.###.4/knoppix-tftpboot/px...noppixboot
set 210:string tftp://###.###.###.4/knoppix-tftpboot/
imgload knoppix-tftpboot/knoppix.0
boot knoppix.0


But now, I'm attempting to get iscsi to connect as a cache location for data recovery. Here's my code and the error messages:

set iscsistuff iscsi:###.###.###.6::::iqn.2017-11.nnnn-iscsitrgt.nnnn.local:knoppix00 iqn.2017-11.nnnn-iscsitrgt.nnnn.local:knoppixstuff
sanhook ${iscsistuff} && sanunhook || echo Unable to hook ${iscsistuff}
set 209:string http://###.###.###.4/knoppix-tftpboot/px...noppixboot
set 210:string tftp://###.###.###.4/knoppix-tftpboot/
imgload knoppix-tftpboot/knoppix.0
boot knoppix.0

The error is:
Could not open SAN device: Input/ouput error (http://ipxe.org/1d0d6139)

I can connect via Windows iscsi initiator using the initiator name:
iqn.2017-11.nnnn-iscsitrgt.nnnn.local:knoppixstuff

Once connected, I can delete, create, and format the filesystem and I can create directories and files. But when attempting via iPXE I get the above error.

Any ideas?
